Lebanese students views about knowing and learning science are surveyed and correlated with course achievement and teaching practice. The Views about Sciences Survey (VASS) was revised to this end, and administered to over two thousand Lebanese…

Collaboration scripts are usually implemented as parts of a particular collaborative-learning platform. Therefore, scripts of demonstrated effectiveness are hardly used with learning platforms at other sites, and replication studies are rare. The…

Scanning of the visual scene is an important selective process in visual perception. In this article we argue that eye-movement data provide an excellent on-line indication of the cognitive processes underlying visual search and reading. We outline…

The integrity of the safety case depends primarily on the quality\nof the reasoning embodied in the safety argument and the trustworthiness\nof the associated items of evidence. Safety case arguments, often\ndepicted using graphical notations such…

When designing learning and assessment environments it is essential to articulate the underpinning education philosophy, theory, model and learning style support mechanisms that inform their structure and content. We elaborate on original PhD…

Advancing the art and science of education practice requires a robust evaluation of the relationship between students' exposure to learning and assessment environments and the development of their cognitive competence (knowing that and why) and…

Mutations in the POU domain gene Brn-3c causes hearing impairment in both the human and mouse as a result of inner ear hair cell loss. We show here that during murine embryogenesis, Brn-3c is expressed in postmitotic cells committed to hair cell…

Storytelling is an ancient art that allows us to share experiences, thoughts and values. In the oral tradition, stories were told in a conversational way by the elders in order to give indirect advice and communicate morals. Each culture or…

When facilitating asynchronous discussion forums, should online instructors be encouraged to take a prominent 'sage on the stage' role, a more constructivist 'guide on the side' role, or an ultra low profile as 'the ghost in the wings'? There is no…

This study examined faculty characteristics and behaviors in 46 MBA courses conducted over a two-year period. We found that both formal instructor activities, referred to in the online learning literature as teaching presence, and informal…

SAGE is a framework for number theory, algebra, and geometry computation\nthat is initially being designed for computing with elliptic curves and modular\nforms. The current implementation is primarily due to William Stein. It is open\nsource and…

"My work has had nothing to do with gay liberation," Michel Foucault reportedly told an admirer in 1975. And indeed there is scarcely more than a passing mention of homosexuality in Foucault's scholarly writings. So why has Foucault, who died of…

A proposal for saliency computation within the visual cortex is put forth based on the premise that localized saliency computation serves to maximize information sampled from one's environment. The model is built entirely on computational…

Salvia divinorum (salvia) is an intense, short-acting hallucinogenic plant gaining popularity among adolescents in the United States. There has been little scientific documentation of salvia's effects. The popular video-sharing website YouTube has…

In this work we examine nine different sources for user similarity as reflected by activity in social media applications. We suggest a classification of these sources into three categories: people, things, and places. Lists of similar people…

The authors examined whether 13- to 15-year-old adolescents who experience feelings of same-sex attraction (SSA) differ from those without such feelings in the quality of relationships with parents, peers, and class mentors and in psychosocial…

Abstract: Manual creation of metadata is tedious, error-prone and doesn’t scale. As the amount of learning content continues to grow, it becomes less and less feasible to describe all available content manually. Moreover, the metadata humans create…

The number of individuals to include in a research study, the sample size of the study, is an important consideration in the design of many clinical studies. This article reviews the basic factors that determine an appropriate sample size and…

A common misconception about sampling in qualitative research is that numbers are unimportant in ensuring the adequacy of a sampling strategy. Yet, simple sizes may be too small to support claims of having achieved either informational redundancy or…
